Help.  Why is it so difficult to understand the documentation? What on earth is ARP? All I want to do is specify which systems can log in using wifi. Life was much simpler with the stupider Linksys router. I thought I was reasonably intelligent but cannot for the life of me figure out the documentation and what to do. I thought I had the MAC addresses loaded correctly but now nothing works. Not even if I turn off the security.

Fortunately the admin password is working. The login password has been rejected but I didn't reboot the router.

Is there a TPLink for Dummies book anywhere around?
